It manufactures complex shapes and precise dimensions through steps such as mixing metal powder with lubricants, pressing, and sintering. Powder metallurgy gears have been widely used in fields such as automobiles, aerospace, and precision instruments due to their high strength, high precision, and the ability to manufacture complex shapes. However, the existing feeding structures for powder metallurgy gear production still have certain deficiencies in terms of efficiency, precision, adaptability, cost, and maintenance, and further technological improvements and innovations are needed.

[0036] Specifically, a protective shell 17 is connected to the outside of the electric controller 907. The function of the protective shell 17 is to protect the internal electric controller 907 from the external environment. The bottom end of the protective shell 17 is connected to a fixing block 18 to ensure the stability and reliability of the protective shell 17. The fixing block 18 can serve as a support point to enhance the fixing effect of the protective shell 17. A material guide pipe 19 is arranged at the middle left of the top end of the storage box 902. One end of the material guide pipe 19 is connected to the storage box 902, and the other end is connected to an auxiliary ring 20.

In addition, the right side of the top end of the storage box 902 is fixed to a connecting plate 21, and two vibration motors 22 are connected to the top end of the connecting plate 21. The vibration motors 22 are used to vibrate the metallurgical powder inside the storage box 902 to ensure that the weight of the metallurgical powder stored inside the storage box 902 reaches the specified weight.

[0037] Working principle: When the device is needed to feed metallurgical powder, the feeding trough 4 installed through the central part of the first fixing plate 2 facilitates the feeding of metallurgical powder. A suction pipe 5 is provided at the upper right end of the middle part of the feeding trough 4. One end of this suction pipe 5 is connected to the feeding trough 4, and the other end is fixedly connected to a suction pump 6. The suction pump 6 can efficiently suck the metallurgical powder from the suction pipe 5 and convey the material to the screening box 8 through a discharge pipe 7 connected to its right end. The screening box 8 is used to screen and separate the sizes of metallurgical powder particles to ensure that only qualified metallurgical powder can be sent out. At the upper middle part of the inner side wall of the screening box 8, a first sieve 10 is provided. The middle bottom end of this sieve 10 is fixedly connected to a top-type vibrator 11. The function of this top-type vibrator 11 is to make the metallurgical powder be effectively screened on the sieve 10 through vibration. At the lower middle part of the top-type vibrator 11, a second sieve 12 is also provided. This sieve 12 further finely screens the metallurgical powder to ensure the quality and precision of the metallurgical powder. The middle bottom end of the screening box 8 is communicated with a blanking pipe 13. The function of this blanking pipe 13 is to send out the screened metallurgical powder. A flow-limiting valve 14 is fixedly connected to the middle part of the blanking pipe 13. This flow-limiting valve 14 can control the flow rate of the metallurgical powder to ensure that the conveying speed and quantity of the metallurgical powder meet the production requirements. Such a design not only ensures the smooth conveying of the metallurgical powder but also ensures the quality of the metallurgical powder and the stability of production. At the same time, by fixing a cross beam on the bottom plate and opening a limiting groove 905, and opening a groove 901 on the bottom plate 1 and installing a storage box 902, and fixing limiting blocks 903 at the front and rear ends of the middle part of the storage box 902. Both of the two limiting blocks 903 are slidably connected to the inner side wall of the limiting groove 905. Such a design enables the limiting blocks 903 to move flexibly in the limiting groove 905 while maintaining sufficient stability to ensure that the position of the storage box 902 can be accurately restricted during the movement of the storage box 902. At the same time, the electric controller 907 controls the push rod 906 to drive the storage box 902 to slide in the groove 901, so that the metallurgical powder in the storage box 902 automatically falls into the molding machine, and after the feeding is completed, the storage box 902 automatically retracts to its original position for feeding, reducing manual intervention and improving the production efficiency of the gear.
